Commit de0aa7b2 ("PCI: hv: Fix 2 hang issues in hv_compose_msi_msg()") uses local_bh_disable()/enable(), because hv_pci_onchannelcallback() can also run in tasklet context as the channel event callback, so bottom halves should be disabled to prevent a race condition. With CONFIG_PROVE_LOCKING=y in the recent mainline, or old kernels that don't have commit f71b74bc ("irq/softirqs: Use lockdep to assert IRQs are disabled/enabled"), when the upper layer IRQ code calls hv_compose_msi_msg() with local IRQs disabled, we'll see a warning at the beginning of __local_bh_enable_ip(): IRQs not enabled as expected WARNING: CPU: 0 PID: 408 at kernel/softirq.c:162 __local_bh_enable_ip The warning exposes an issue in de0aa7b2: local_bh_enable() can potentially call do_softirq(), which is not supposed to run when local IRQs are disabled. Let's fix this by using local_irq_save()/restore() instead. Note: hv_pci_onchannelcallback() is not a hot path because it's only called when the PCI device is hot added and removed, which is infrequent.

Before 8d85a7a4 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0"), pci_sriov_set_totalvfs(pdev, 0) meant "we can enable TotalVFs virtual functions". After 8d85a7a4, it means "we can't enable *any* VFs". That broke this scenario where nfp intends to remove any limit on the number of VFs that can be enabled: nfp_pci_probe nfp_pcie_sriov_read_nfd_limit nfp_rtsym_read_le("nfd_vf_cfg_max_vfs", &err) pci_sriov_set_totalvfs(pf->pdev, 0) # if FW didn't expose a limit ... # userspace writes N to sysfs "sriov_numvfs": sriov_numvfs_store pci_sriov_get_totalvfs # now returns 0 return -ERANGE Prior to 8d85a7a4, pci_sriov_get_totalvfs() returned TotalVFs, but it now returns 0. Remove the pci_sriov_set_totalvfs(pdev, 0) calls so we don't limit the number of VFs that can be enabled.

The TotalVFs register in the SR-IOV capability is the hardware limit on the number of VFs. A PF driver can limit the number of VFs further with pci_sriov_set_totalvfs(). When the PF driver is removed, reset any VF limit that was imposed by the driver because that limit may not apply to other drivers. Before 8d85a7a4 ("PCI/IOV: Allow PF drivers to limit total_VFs to 0"), pci_sriov_set_totalvfs(pdev, 0) meant "we can enable TotalVFs virtual functions", and the nfp driver used that to remove the VF limit when the driver unloads. 8d85a7a4 broke that because instead of removing the VF limit, pci_sriov_set_totalvfs(pdev, 0) actually sets the limit to zero, and that limit persists even if another driver is loaded. We could fix that by making the nfp driver reset the limit when it unloads, but it seems more robust to do it in the PCI core instead of relying on the driver. The regression scenario is: nfp_pci_probe (driver 1) ... nfp_pci_remove pci_sriov_set_totalvfs(pf->pdev, 0) # limits VFs to 0 ... nfp_pci_probe (driver 2) nfp_rtsym_read_le("nfd_vf_cfg_max_vfs") # no VF limit from firmware Now driver 2 is broken because the VF limit is still 0 from driver 1.

Commit 51bc085d ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.

An SHPC can be operated either by platform firmware or by the OS. The OS uses a host bridge ACPI _OSC method to negotiate for control of SHPC. If firmware wants to prevent an OS from operating an SHPC, it must supply an _OSC method that declines to grant SHPC ownership to the OS. If acpi_pci_find_root() returns NULL, it means there's no ACPI host bridge device (PNP0A03 or PNP0A08) and hence no _OSC method, so the OS is always allowed to manage the SHPC. Fix a NULL pointer dereference when CONFIG_ACPI=y but the current hardware/firmware platform doesn't support ACPI. In that case, acpi_get_hp_hw_control_from_firmware() is implemented but acpi_pci_find_root() returns NULL.
